Meline Engineering was hired by Bovis Lend Lease, Inc. to provide engineering support services for the ground heat exchanger under construction at the Balboa Reservoir in San Francisco, CA. The ground heat exchanger is connected to a central plant system in a Joint Use Facility, which in turn provides hot and chilled water for the heating, ventilating and air conditioning systems in the Joint Use Facility and in three additional buildings at City College of San Francisco.

Meline Engineering conducted a third party review of the construction documents and provided input to the engineer of record and the general contractor for best practices associated with the ground heat exchanger. Meline Engineering’s role was extended through the construction phase of the ground heat exchanger to provide regular inspections of the site and to review related RFIs, submittals, shop drawings and change orders in collaboration with the engineer of record. The installation of the ground heat exchanger with stub-out for future connection to the central plant was completed in 2009.
